Gunther green, steam bully

Trample, prowess

When Gunther green enters the battlefield smash 4 (search target players library for up to 4 target
artifacts and/or creatures with mana value 2 or less,
put them in their owners graveyard, they shuffle.)

Whenever Gunther green attacks with stats greater
than it’s base stats, target a artifact or creature with
mana value 2 or less, you may cast that card until
the end of turn.
